Question 1 Not yet graded / 1 pts (Q001) Work with a group of your classmates or on your own to review the two karyotypes on p. 43 of your lab manual and answer the questions in this exercise. Note that the karyotypes provided depict single chromosomes, rather than homologous pairs. Describe two things the two karyotypes have in common. Your Answer: The two karyotypes, human and chimpanzee, share several similarities. First, both display 23 pairs of chromosomes, with one pair being the sex chromosomes. Second, they exhibit similar banding patterns on their chromosomes, indicating conserved genetic material. These commonalities highlight the evolutionary relationship between these species. Question 2 Not yet graded / 1 pts (Q002) Describe two things that differ between the karyotypes. Your Answer: Karyotypes, a visual representation of an individual's chromosomes, exhibit variations among species. First, the number of chromosomes differs; humans possess 46 while dogs have 78. Second, the arrangement and size of chromosomes vary; humans display a distinctive XY sex determination system while birds showcase ZW. These differences reflect genetic diversity across organisms. https://ilearn.laccd.edu/courses/267723/quizzes/21511337?module_item_id=17591563 1/2
3/25/24, 7:21 PM LAB 02 EXERCISE 03: ANTHRO 111 : Lab Human Bio Evol - Rigby J. - SPRING 2024 - SECTION# 17489 Question 3 Not yet graded / 1 pts (Q003) How do you know this karyotype is from a human? Your Answer: The study of karyotypes has enabled scientists to identify and classify genetic disorders. By analyzing the number, size, and shape of chromosomes, we can determine if a karyotype belongs to a human. The presence of 23 pairs of chromosomes, including two sex chromosomes, confirms its human origin. Question 4 1/1 pts (Q004) Which karyotype is from a human? Animal 1 Correct! Animal 2 FEEDBACK: The karyotype of Animal 2 is from a human. Question 5 1/1 pts (Q005) Which karyotype is from a chimpanzee? Correct! Animal 1 Animal 2 FEEDBACK: The karyotype of Animal 1 is from a chimpanzee. Question 6 Not yet graded / 1 pts (Q006) How do you know this karyotype is from a chimp? Your Answer: The identification of a chimp karyotype requires careful analysis. By examining the number, size, and banding patterns of chromosomes, scientists can differentiate between species. The presence of 48 chromosomes, similar to humans, along with specific chromosomal arrangements and distinctive banding patterns, confirms this karyotype as belonging to a chimp. Quiz Score: 6 out of 6 This quiz score has been manually adjusted by +4.0 points. https://ilearn.laccd.edu/courses/267723/quizzes/2151133?module_item_id=17591563 2/2

Put the following steps into the correct order of events.
= Pull the slide back and release to chamber the first round
= Squeeze the trigger, releasing the firing pin
= The firing pin striker the primer, igniting the powder
= Insert the loaded magazine
= The slide moves to the rear (again), then slides forward, chambering the next round
= Cock the hammer back, which pulls the firing pin back
= Gases build inside the casing, until the bullet is forced out the casing, down the barrel and out of the muzzle
